action

Inspired by Cobra. Cobra is a library for creating powerful modern CLI applications. "action" can be used to create a more fine-grained behavior of a command.

Getting Started

cmd := &cobra.Command{
    Use:   "example-cmd",
    Short: "A sample command.",
    RunE: func(cmd *cobra.Command, args []string) error {
        act := &action.Action{
            Name: "example-action",
            Run:  func(act *action.Action) error { return nil },
        }
        
        _ = act.AddAction(
            newSubAction1(),
            newSubAction2(),
        )

        act.Execute()
    },
}

func newSubAction1() *action.Action {
    return &action.Action{
        Name: "sub-action1", 
        Executable: func(act *action.Action) bool {
            // do something
            return true
        },
        Run:  func(act *action.Action) error { return nil },
    }
}

func newSubAction2() *action.Action {
    return &action.Action{
        Name: "sub-action2",
        Executable: func(act *action.Action) bool {
            // do something
            return false
        },
        Run:  func(act *action.Action) error { return nil },
    }
}

• Executable: whether is an executable action.
• action.Execute() will find the first executable action of the root action and execute it. If no executable action can be found, run the current action.
